by Casper and Amerisleep are two of the finest brands when it comes to memory foams. They are trendy for their quality and long-lasting mattresses. While Amerisleep focuses more on its memory foam range, Casper offers its range of memory foam mattresses and hybrids (check the top rated hybrid mattresses).
But which one of them should you consider for your bedroom?
In this guide, we will shed some light on which one of them is the better option for you and why.

The Key Differences Between Amerisleep Vs. Casper
Who The Amerisleep AS3 is Best For
Best for…
People who look for cushioned support: If you are looking for a mattress with cushioned support, you will find the AS3 mattress by Amerisleep the best. The medium-firm feel of this memory foam mattress is unmatchable.
Those who want durability: This mattress is one of the most long-lasting mattresses you will find on the market. With a durable base foam, it will continue to serve you for a long time.
Better blood circulation: This mattress will keep you cool and boost your blood circulation. The mattress achieves this by converting your body heat into far infrared energy.
May not be best for…
Strict stomach sleepers: The mattress works well if you are a combination sleeper. But if you strictly prefer sleeping on your stomach, you need to consider another mattress. For that, you will need a firmer mattress that prevents sagging from the center (also check 10 great toppers for sagging mattress).
Hot sleepers: The mattress does a pretty decent job with its Bio-Pur layer to keep you cool at night, but if you tend to sleep hot, it won’t work out well for you, especially during the hotter days (check the top rated cooling mattresses for hot sleepers).
Who The Casper Original Is Best For
Best for…
Combo sleepers: If you don’t have any preference regarding your sleep position, then the Casper Original mattress will work fine for you.
Better airflow: The hybrid variant of this mattress is pretty good because it boosts airflow while you are on your mattress. You won’t have to worry about sleeping hot on this mattress.
Excellent conformance: The all-foam variant is pretty good regarding maximum conformance. And if you are a fan of that enveloping feel, you will love sleeping on this mattress.
May not be best for…
Motion isolation: The all-foam variant would be better if you want better motion isolation. The hybrid versions won’t be that great and won’t work if you want to share your mattress with your partner, who moves a lot at night.
Hot sleepers: The hybrid versions would be a good choice, but the all-foam variant is not. You will feel uncomfortable on this mattress if you tend to sleep hot, despite featuring a cool comfort layer.
Top Features Compared – Amerisleep Vs. Casper
Construction
The AS3 features an ultra-breathable comfort layer right at the top as it’s over that prevents overheating. And it is followed by Amerisleep’s very own Bio-Pur open-cell layer that ensures that the foam contours well to your body and stays responsive.
The targeted pressure-relief system guarantees perfect alignment to your pressure points (also check the best selling mattress toppers for pressure points). And right at the end is the Bio-Core base layer made of quality materials to ensure high durability and prevent sagging over time.
This mattress does a pretty fine job when it comes to durability despite being memory foam. Memory foam mattresses are not known for their durability, but we can say that AS3 Amerisleep mattress is an exception. And that is precisely why the mattress is covered under a 20-years warranty.
Casper Original Mattresses has two different variants. The All-foam variant features an AirScape layer right at the top that increases the overall breathability of the sleep surface. The second layer is all about providing zoned support to your body.
It features three ergonomic zones that gently allow your body to sink into the mattress. Thanks to the zoned support, this mattress stays soft around the shoulders and firm around the waist, lower back, and hips (also check 10 great mattress toppers for hip pain).
Then there is the base layer which is made of durable foams, and it’s there to prevent sagging while providing proper support to your body. The overall construction of their hybrid variant is pretty similar to the all-foam variant, but there is a slight difference.
After the zoned support layer and before the base layer, Casper has added resilient springs or coils. They provide better edge support and airflow to the mattress.
This feature makes this mattress ideal for stomach sleepers and those after better edge support. Hot sleepers can benefit from these coils thanks to the better airflow.
Firmness
The AS3 new mattress is rated around 7 out of 10 on the firmness scale. It is a good option for anyone looking for a medium-firm mattress.
Medium-firm mattresses work better for combination sleepers. They provide enough support to all their body parts. These mattresses strike a perfect balance between support and cushioning.
The mattress contours well according to your body shape and will work well if you weigh under 230 lbs.
Firmer mattresses are better than plush mattresses in terms of durability as well. This mattress firmness level will work well for you if you tend to deal with low back issues or other joint pains.
The Casper Original mattress has two different variants that work differently regarding foam firmness. The all-foam variant of the Casper Original mattress is a good choice for better conformance. This mattress comes with a medium configuration.
It means this mattress is particularly ideal for side and back sleepers. With decent support, you will always get that sinking feeling as the mattress conforms to your body shape.
On the other hand, the hybrid variant of this mattress comes with a slightly firmer feel compared to the all-foam variant. It means this mattress is an ideal choice for combo sleepers. So, if you like to sleep on your stomach, this mattress will work fine.
The comfort foam layer of the mattress will provide you with the much-needed conformance and cushioning, while the coils and base layer provides enough support to keep your spine properly aligned.
This is precisely why the hybrid variant of the Casper Original mattress is a good choice for most sleepers out there, even if you weigh over 230 lbs.
Motion Isolation and Edge Support
Being a memory foam mattress, the AS3 is a good option if you are looking for excellent motion isolation. Like most other memory foam mattresses, this mattress is an ultimate choice for isolating motion. So, if you want to share your bed with your partner, who tends to move a lot at night, the AS3 is a good option.
But the same cannot be said for this mattress if we talk about edge support. Generally, memory foam mattresses are not that great when it comes to edge support. And this is exactly what the case is with the AS3 by Amerisleep. Hence, if you are looking for this particular feature, you must look elsewhere.
The all-foam variant of the Casper original mattress is similar to the AS3 by Amerisleep. As a memory foam mattress, it does a fine job isolating motion. So, if you want to share your bed with your partner who moves around during sleep, this is a dreamy choice (check the best selling mattresses for couple).
The hybrid variant of the Casper Original Mattress is not that advisable in terms of motion isolation. As with most other hybrid or innerspring mattresses, motion isolation is not their strongest feature. The same can be said for the Casper Original Hybrid mattress. So, this is not the right choice to share with your partner, who moves around a lot in sleep.
But hybrids and innerspring mattresses offer unrivaled edge support, one of their stronger features. The Casper Original mattress’s hybrid variant offers plenty of edge support.
This feature is not there in the all-foam variant of this mattress. Memory foam mattresses are generally not good in terms of edge support, which is the case with the all-foam variant of the Casper Original mattress.
Temperature Regulation
The Amerisleep AS3 is a memory foam mattress, so temperature regulation will not be its most vital point. However, the mattress comes with a Bio-Pur memory foam layer right at the top specifically designed to dissipate heat from your body and allow you to sleep comfortably and cool.
But if you are a hot sleeper, this feature will only work for a short time. You will have to regulate your room temperature to make it work better. The medium-firm feel of the mattress contributes to temperature regulation as well.
It’s because plushier mattresses trap heat as your body sinks into the sleep surface. Still, in comparison to other mattresses such as latex or hybrids, a memory foam mattress with an open-cell top layer slightly underperforms. So, you need to keep this particular thing in your mind.
The all-foam variant of the Casper Original mattress performs pretty similar to AS3 as it is a memory foam mattress. Memory foam mattresses are not that great when it comes to temperature regulation.
They are designed to trap heat from your body and provide that warm and cozy feeling. This is precisely why so many people love sleeping on these memory foam. But if you are one of those who tend to sleep hot, then the same trapped body heat will start causing discomfort (check 10 mattresses with great comfort).
But the Casper Original mattress hybrid variant is a much better performer in this department. As it is a hybrid mattress and features a coil in its construction, this mattress promotes airflow better. With high breathability, heat from your body doesn’t get trapped inside the mattress. As a result, you will continue to sleep on a relaxed surface.
Position and Body Type
As a memory foam mattress, the AS3 is a good option for side and back sleepers. It does come with a medium-firm feel, so it can work for combination sleepers.
But you have to remember that it is not firm enough for you; if you are strictly a stomach sleeper, your hips will begin to sag into the mattress, resulting in back pain and disruption if you continue to sleep on this surface.
It is a good option for anyone who doesn’t weigh more than 230 lbs, the mattress provides enough support for this weight limit. However, if you weigh more, your spine will not run properly aligned, and your back will start hurting if you continue to sleep on this mattress (also check 10 great mattresses for overweight people).
The all-foam variant comes with a medium-firm configuration. It is a decent option for side and back and combo sleepers, just like the AS3 (check the best selling mattresses for side sleepers). It will work pretty well for anyone who weighs under 230 lbs.
But it is not a good choice for stomach sleepers or people who weigh over 230 lbs. The reason for this that is the mattress begging to sag from the center, and it will cause your spine to misalign, which will result in lower back pains (check 10Â amazing mattresses for back pain).
The hybrid version is better for people who weigh over 230 lbs and those who prefer to sleep on their stomachs. It is much firmer than the all-foam variant, which is why it can provide better support rather than cushioning.
Price Range
Going through the table, you will notice that the AS3 is a much cheaper option than the Casper Original mattress despite the fact that Amerisleep offers better after-sales service in terms of a 20-year warranty which is way more than what Casper has to offer (check 10 great mattresses under $1,000).
But you also have a choice with Casper, as you can either go for an all-foam mattress or a hybrid one. Still, you will notice that the Casper Original mattress doesn’t come in split king size (also check 10 top-quality split king mattresses).
| Amerisleep Mattresses | Casper Mattresses | |
| Twin | $699 | $895 |
| Twin XL | $749 | $995 |
| Full | $899 | $1195 |
| Queen | $949 | $1295 |
| King | $1249 | $1695 |
| Cal King | $1249 | $1695 |
| Split King | $1648 | – |
Key Differences in Trial Periods and Warranties
Amerisleep offers one of the most generous trial periods at 100 nights, compared to Casper’s 100 nights. This gives you ample time to adjust to the new mattress and decide if you want to keep it or not. The 20-year warranty from Amerisleep is also double what Casper provides at 10 years. This demonstrates Amerisleep’s confidence in the quality and durability of their mattresses.
Don’t underestimate the value of a good trial period and strong warranty when shopping for a new mattress. The fine print can make a big difference down the road if any issues come up. Carefully comparing these policies can help you determine which brand stands behind their products for the long haul.
Verdict
Both Amerisleep AS3 and Casper are pretty high-quality mattresses (check the best selling mattresses). But Casper has taken the lead here because it provides its customers with an option to either go for an all-foam mattress or a hybrid mattress.
Suppose you are looking for a budget-friendly option without compromising on quality (check 10 amazing mattresses under 2,000 dollars). In that case, Amerisleep is the better option as it offers a 20-year warranty, which is double the warranty of Casper.
